Spermatozoa Cell Markers

A spermatozoon or spermatozoan (pl.spermatozoa), from the ancient Greek σπέρμα (seed) and
ζῷον (living being) and more commonly
known as a sperm cell, is the haploid cell that is the male
gamete. It joins an ovum to form a zygote. A zygote is a single
cell, with a complete set of chromosomes, that normally develops
into an embryo.

a key enzyme responsible for the irreversible
transformation of androgens into estrogens, is expressed in
human ejaculated spermatozoa: a putative marker of motility.

CD46

restricted to
spermatozoa and their immediate precursors in the testis.
PMID: 15601919

Inhibin B

Serum inhibin B level seems to be more
accurate than serum FSH level in prediction of the presence of
testicular spermatozoa in patients with nonobstructive
azoospermia.

Mannitol

an effective extracellular marker for human
spermatozoa if concentrations greater than or equal to 0.3 mM
are used.
PMID: 6415273

Protamine 1 and 2

suitable markers for spermatozoa because they
are exclusively expressed in the haploid genome and that
protamine mRNA can be detected in semen stains by the highly
sensitive reverse transcriptase-polymerase chain reaction
(RT-PCR).

TEPA

A marker for use in evaluating fertilizing
ability of rabbit spermatozoa in competitive fertilization.
